Sullivan County sits at the center of the Tri-Cities region of northeast
Tennessee, with a scenic skyline, miles of mountains in the Cherokee
National Forest, and three large lakes built by the Tennessee Valley
Authority. Well-known county crossroads include Colonial Heights and
Bloomingdale, while famous local landmarks include Warriors Path State
Park; the stalagmites of the Appalachian Caverns and Bristol Caverns;
the World's Fastest Half-Mile Track at Bristol Motor Speedway; the
Birthplace of Country Music at Bristol; and the Grand Guitar, the
world's only guitar-shaped museum. Piney Flats is the home of Rocky
Mount, once the capitol building of the Territory of the United States
South of the River Ohio. Bluff City boasts railroad history and Civil
War stories along the South Fork of the Holston River. Kingsport lays
claim to Netherland Inn, Bays Mountain Park, and the Long Island of the
Holston, a sacred place for the Cherokees. The courthouse town of
Blountville holds the distinction of being the only county seat in
Tennessee that is not incorporated.
